One thing I learned about China a few weeks ago; supposedly, when Australia spoke up slightly about not liking something China had done, China knee jerk reacted and embargoed Australian tanker shipments. Many tankers were loaded with coal. China is dependent on outside energy to bolster its manufacturing and infrastructure and wasn’t paying attention to the long term effects of blocking Australian coal (ego and all that…) and they have used a great deal of their reserves of coal. Rumor is that Russia has redirected some of the gas from Europe to China. Gas isn’t coal, but the two may be tying together energy wise, if the info was correct
